| Updated: 4:06 p.m. Your blood type won’t have much effect on whether you catch COVID-19, or have a severe case of the disease, according to a new study by researchers at Intermountain Healthcare — a conclusion that contradicts earlier research. “It’s wonderful to know your blood type,” Dr. Jeffrey L. Anderson, a physician at Intermountain Medical Center’s Heart Institute in Murray, said Thursday. “But knowing what your blood type is is not something that will protect you from COVID, or put you at higher risk.” The researchers at Intermountain examined the outcomes of more than 100,000 patients who were tested for the coronavirus. Connections between specific blood types and the virus “are unlikely and will not be useful factors associated with disease susceptibility or severity,” the study concluded.
